This is how Twilight vs. Tuma goes in My Little Pony Transformers Prime Bionicle: The Legend Reborn.
[Twilight stands about the weakened Makuta when she hears clapping and sees Tuma clapping while approaching her. Tuma then stops clapping]
Tuma: Yes. Kill him. He was weak, broken. Kill him and you can take your rightful place at my side as my apprentice.
Mata Nui: No!
[Mata Nui is about to interfere when Tuma blasts him with a zap of electricity]
Shining Armor: Help him!
[Twilight looks at Mata Nui and then at Makuta, who's getting back up. Twilight thinks then has a brainwave]
Twilight Sparkle: That's it!
[She blasts Tuma with magic then kicks him into a wall]
Tuma: You should've killed Makuta, you could've ruled by my side.
Twilight Sparkle: That's what you think. I will never give in to my hatred.
[She zaps Tuma]
Tuma: End this conflict and rise above this. Applejack, Pinkie Pie, Rarity, Fluttershy, and Rainbow Dash mean nothing to you.
Twilight Sparkle: They are my friends! I would never turn my back on them! Even if you try to presuade me to!
[She zaps him again]
Tuma: Their annoyance gives you anger. Embrace it.
Twilight Sparkle: No way!
[She zaps him again]
Tuma: Don't you wanna know where you came from?
Twilight Sparkle: No!
[Tuma gets up]
Tuma: They are traitors. They would never treat you as a friend.
Twilight Sparkle: I know a liar when I see one and I'm staring right at him.
Tuma: If you wish to go against me, so be it.
Twilight Sparkle: It is so on!
[They start fighting]
Tuma: You need a teacher. I can teach you everything I know.
Twilight Sparkle: I was a student. But I have a student of my own, now. Starlight Glimmer!
[Starlight teleports in front of Tuma]
Tuma: I'll be honest, your fight styles impress me.
Twilight Sparkle: Well, you should see my magic.
[She blasts him with a beam of magic]
Twilight Sparkle: If you think that's impressive, watch this.
[Twilight subdues Tuma with a big blast of magic]
Tuma: You are quite powerful.
Twilight Sparkle: But I will never join you.
[Lightning bolts come out of Tuma's fingers but Twilight absorbs the lightning and fires an amount of magic at Tuma. Tuma tries to get back up, but is unable to stand. Tuma collapses on his knees and Twilight readies her horn]
Twilight Sparkle: You've taken everything from me!
Tuma: Your feelings for your friends are not real.
Twilight Sparkle: Yes they are!
[Twilight prepares to shoot him when Mata Nui, Ackar, Kiina, and Gresh come over to her]
Mata Nui: Wait!
Twilight Sparkle: You want him dead as much as I do!
Mata Nui: Yes, but not yet! Not until he's told us Makuta's secrets!
Twilight Sparkle: You wanna take him prisoner?
Mata Nui: To a place where we can interrogate him. Put him on trial for crimes against Equestria and Bara Magna. Then, we'll execute him, to show everyone that we don't have to fear him anymore.
Twilight Sparkle: If I let him live, he'll haunt me forever.
Mata Nui: He is the only one who knows about Makuta's true plan. He can't tell us if he's dead.
Tuma: Strike me down. It is your destiny.
Mata Nui: Not yet, she won't.
[Twilight's horn stops glowing and she steps back. Mata Nui then draws his sword and aims it at Tuma]
Mata Nui: [to Ackar] Get something to hold him.
[Twilight watches as Ackar brings a vine]
